There is provided an epoxy resin composition containing an epoxy resin, a solid basic compound, and a polythiol. By preparing a mixture 1 by kneading the epoxy resin with the solid basic compound, and then kneading the polythiol therewith, the dissolution of the solid basic compound into the polythiol is rate-limited to ensure the pot life, and due to a catalyst action by the dissolution of the solid basic compound at a time of heating, heat curability in a short time is realized.
